Prior to commit f41fc1e, the CI workflow .github/workflows/validation.yml runs on pull_request and executes code supplied by the pull request before any maintainer review. Three PR-editable files drive this: \"requirements.txt\", \".pre-commit-hooks-config.yaml\" / \".pre-commit-yamlfmt-config.yaml\", and \".gitmodules\". A contributor with no special repository access could open a pull request that modifies these files and have their code run on the CI runner. This issue has been patched via commit f41fc1e.","categories":["Unclassified"],"product":"devicetype-library","vendor":"netbox-community","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-55251","source_modified_at":"2026-10-05T20:19:04.856Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"devicetype-library","vendor":"netbox-community","versions":[{"version":"< f41fc1e48dec8d7d31afba5f13a8c73652ff5796","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00107,"percentile":0.01117,"score_date":"2026-10-23"},"published_at":"2026-10-01T19:49:32.741Z","modified_at":"2026-10-05T20:19:04.856Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-55251","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-05T20:19:04.856Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-55251","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/netbox-community/devicetype-library/security/advisories/GHSA-5x2m-x42f-g4cm","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/netbox-community/devicetype-library/commit/f41fc1e48dec8d7d31afba5f13a8c73652ff5796","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-05T20:18:57.761621Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-05T20:19:04.856Z","content_hash":"46d5f936acdab9e93888409621134169c9a0ea57a0458d47611a6a598668081c"}}
